During the 20th National Congress, leader of Hunan Province introduced the advantages of Hunan in the construction machinery industry:

1. In the time for a cup of tea, more than ten thousand parts of a locomotive were gathered in a 5 km radius.

2. One excavator can be off the line in 5 minutes.

3. Among the top 5 global construction machinery industries, Hunan accounts for 2.

From the above 3 points, we can see that there are 2 key technologies in the Chinese market: a complete industry and technology chain and the world's largest market. This is the speed of China and the advantage of China's machinery industry. I think any organization in the machinery industry can hardly be separated from China. This is also the reason why big brands, such as SUN... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVE

Bekov is from a Russian hydraulic equipment company. Most of the hydraulic manifolds in the past 3 years were purchased from Ningbo and went smoothly. A batch of hydraulic manifolds purchased last time stumped him due to the precision of valve block holes. At the beginning of the year, their customer customized a hydraulic power unit. From the perspective of hydraulic manifold alone, it was not difficult, but the requirements for the accuracy of the valve block bore diameter were high. He chose a hydraulic manifold manufacturer in Ningbo who had cooperated for 3 years to place the order. He thought that the PO was confirmed by the supplier and his work was completed, but from the start of the sample, trouble came.

After 50 days, the hydraulic manifold manufacturer advised... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

Cleveland is from a hydraulic equipment company in Mexico. He has purchased hydraulic valves in Ningbo for 3 years. We have communications for two times. He is confident, but the hydraulic cartridge relief valves he purchased last time stumped him. At the end of last year, their customer customized a hydraulic paper cutter, which requires the use of a hydraulic cartridge relief valve. The engineer asked Cleveland to purchase SUN hydraulic cartridge relief valve standard parts, and the equipment commissioning was smooth. The customer was satisfied and placed the first batch of orders. Cleveland placed the order with a hydraulic cartridge valve manufacturer in Ningbo. 6 months after the equipment was sold, the customer complained that the stability of the equipment was not as good as the...

AAK HYDRAULIC VALVES

Chapman comes from a hydraulic equipment manufacturing company in Italy. He has been in the company for 3 years and is highly regarded by his boss. However, the hydraulic pilot relief valves purchased at the beginning of the year has been in a big trouble, which makes his boss more and more disappointed with him. They sold a batch of hydraulic power units, and there was squeal or vibration. They judged that it was caused by the abnormality of the hydraulic pilot relief valve. However, when they tested the hydraulic pilot relief valve separately, the parameters met the standard, and no abnormality was found. In a week, Chapman contacted different hydraulic valve manufacturers online and offline, but it was fruitless. The original manufacturer of the hydraulic pilot relief valve could not...

AAK HYDRAULIC VALVES

Pancrazio is from a hydraulic equipment company in Italy. In recent years, his purchase of hydraulic valves in China has been smooth. Recently, he was trapped by a 450bar high pressure hydraulic cartridge relief valve. At the beginning of last year, their new hydraulic power unit was complained by customers about unstable pressure supply 6 months after it was sold. During after sales checking, it was found that the hydraulic cartridge relief valve spool was not flexible. The original manufacturer of the hydraulic cartridge relief valve advised that under 450bar high pressure frequency use, the valve cage was deformed, then the valve spool was not flexible, the only solution is to replace the valves with new ones. Later, with more and more complaints, Pancrazio realized that the service... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVES

For the processing of the main valve hole of the hydraulic cartridge relief valves, AAK uses a new 4-step method instead of the traditional 4-step method, which is 100% burr free. Rubio from Mexico, placed the big order 1 week after the first test order.

Regarding the burrs in the main valve hole of the hydraulic cartridge relief valves, it involves 2 parts: how to effectively avoid and remove them. How to effectively avoid is the root cause. How to remove is the symptoms. AAK focuses on the root cause, while other hydraulic valve manufacturers pay attention to the symptoms. Burr is common in machining. As for how to control the burr in the main valve hole of hydraulic cartridge relief valve, most hydraulic relief valve manufacturers ignore the dead corner in the undercut...

AAK HYDRAULIC VALVE

Go to bed early, read more and exercise more. I have been doing this for 23 years. Do these 3 things every day. If no good result, I will compensate for the failure. One of the most important words I have said to my children is to read or exercise when you don't know what to do.

Go to bed early in order to get up early, do things for 2 hours when your brain is most awake. No matter what you do, the effect is surprisingly good. Read or write, finish 70% of the most important things today. I have been practicing for nearly 23 years.

Read so as not to fall behind. Both skills and cognition need to be constantly improved and expanded. The progress of our predecessors is the ladder for future generations. Absorb knowledge from experts, digest and export, it is sure... Читать дальше (Содержит видео)

AAK HYDRAULIC VALVE

Katherine is from a Greek hydraulic equipment manufacturing company. There were several inquiries for hydraulic cartridge flow control valves with AAK before, but there was no cooperation. In the second half of last year, their customer wanted to customize a set of hydraulic power unit used in aviation equipment. The requirements for hydraulic cartridge flow control valve parameters were: performance of 2 million times, valve hole accuracy with 1μm, high pressure resistance 450bar. Seeing these strict parameter requirements, Katherine ware not sure if there is any hydraulic valve manufacturer who can meet it. More than 10 manufacturers of hydraulic cartridge flow control valves have been contacted, none of them was able to achieve it. Their engineer suggested Katherine contact German HAWE,...

Payne is from a hydraulic equipment company in the United States. His purchase process has been smooth for 3 years. He did not have much cooperation with AAK, until the purchase of a hydraulic pressure control cartridge valve suffered a loss elsewhere, he trusts AAK more and more. 2 years ago, their company sold tunnel boring machines. Less than half a year after sales, customers complained that the equipment was on strike. The after sales worker found that the contact surface between the hydraulic pressure control cartridge valve spool and the valve cage of the hydraulic system of the equipment had signs of wear. It was judged that the leakage led to insufficient pressure supply for the system, and they went on strike. The original manufacturer of the hydraulic pressure control cartridge...
